CONTRACT: Incorporating Coordination into the IP Network Control Plane

Zheng Cai, Florin Dinu, Jie Zheng, Alan L. Cox, T.S. Eugene Ng
2010 2010 IEEE 30th International Conference on Distributed Computing Systems  
This is because an IGP blindly routes traffic along the shortest paths based on link weights, and it is completely oblivious to the interactions between SLA compliance, load balancing and traffic policing  ...  Under this framework, routers continue to operate autonomously, but they also coordinate their actions with a centralized network controller, which evaluates the impact of routing changes, decides whether  ...  As a result, a router not only needs to compute the local routing table rt(x n (t i )), but also needs to compute all-pair shortest path routing state of the entire network, based on its current link state  ...

A localized adaptive proportioning approach to QoS routing

S. Nelakuditi, Zhi-Li Zhang
2002 IEEE Communications Magazine  
We have shown that it is possible to compute near-optimal proportions using only locally collected information.  ...  In QoS routing, paths for flows are selected based on knowledge of resource availability at network nodes and the QoS requirements of flows.  ...  Thus, wdp selects widest paths that are mutually disjoint with regard to bottleneck links. PERFORMANCE EVALUATION We now evaluate the performance of the proposed schemes.  ...

Could Proactive Link-State Routed Wireless Networks Benefit from Local Fast Reroute?

Audun Fosselie Hansen, Geir Egeland, Paal Engelstad
2008 6th Annual Communication Networks and Services Research Conference (cnsr 2008)  
Support for fast and local reroute should therefore be added as a feature to proactive link-state based routing protocols.  ...  To our best knowledge, no published work presents a similar study on fast recovery in proactive link-state routed wireless networks.  ...  Strict local rerouting can be an advantage of proactive link-state routed schemes over reactive multipath schemes where strictly local rerouting cannot always be supported.  ...

We compare the performance of these localized proportional routing models with that of a global optimal proportional model that has knowledge of the global network QoS state.  ...  In this note, we study several issues in the design of localized quality-of-service (QoS) routing schemes that make routing decisions based on locally collected QoS state information (i.e., there is no  ...  Before we proceed to evaluate the performance of these schemes, it is interesting to contrast the link based and path based localized proportional routing models with the global optimal proportional routing  ...

2003 IEEE INFOCOM 2003. Twenty-second Annual Joint Conference of the IEEE Computer and Communications Societies (IEEE Cat. No.03CH37428)  
This paper evaluates these two approaches using two different types of structured overlay: 1) overlays which use a form of generalized hypercube routing, e.g., Chord, Pastry and Tapestry, and 2) overlays  ...  Results show that the tree-based approach consistently outperforms the flooding approach. Finally, for treebased multicast, we show that Pastry provides better performance than CAN.  ...  In particular, we evaluated tradeoffs between the amount of state maintained by each overlay node and routing efficiency, and between different ways of taking advantage of network locality to improve routing  ...
